I use canon 1000d with 18-55mm kit lens, 1-1.5 years old. I feel, my camera's photo quality is getting loss, there is lesser crispness, little blurriness than 1st time when it was new. I can see some dots through view finder & one small object like spider's net when I see a solid coloured objects's image with f22. And I can see the net when I see through the kit lens by my naked eye without using my camera.
Anyone can suggest me what should I do with my camera to get crispness or sharpness back like before? Any sensor cleaning or lens cleaning?
